I was thinking about the mining function M(nounce_of_4_bytes) -> 32_bytes_sha256, and looked at the latest block hash "000000000000000fe5ed4fe9d5d6d976e0e567ccc6484835a9761a3bdf9df8f0".
This 32 bytes number is getting smaller and smaller, and the difficuty is gettting a big jump recently (http://bitcoindifficulty.com/), since if no extraNounce were used, the function M will definitely be a injective function, which means, when difficutly gets larger and larger, the mining will definitely has huge probability of failing and more and more frequently, UNLESS extraNounce were used.
Do you agree? What do you guys think about this?
